PTA is one of the important bulk organic raw materials, widely used in chemical fiber, light industry, electronics, construction and other aspects of the national economy. At the same time, the application of PTA is more concentrated. More than 90% of PTA in the world is used to produce polyethylene terephthalate (PET). It needs 0.85-0.86 tons of PTA and 0.33-0.34 tons of MEG to produce 1 ton of pet. Polyester includes fiber chip, polyester fiber, bottle chip and film chip. In the domestic market, 75% of PTA is used in the production of polyester fiber; 20% is used in the production of bottle grade polyester, mainly used in the packaging of various drinks, especially carbonated drinks; 5% is used in film grade polyester, mainly used in packaging materials, films and tapes. It can be seen that the downstream extension product of PTA is mainly polyester fiber.
Application:
PTA is mostly used in the production of polyethylene terephthalate (polyester). It is an important raw material for polyester fibers, films, plastic products, insulating paints and plasticizers. It is also used in dyes and other products' production.

Aromatic dicarboxylic acids are used as precursors (in form of acyl chlorides) to commercially important polymers, e.g. the fire-resistant material Nomex. Mixed with terephthalic acid, isophthalic acid is used in the production of PET resins for drink plastic bottles and food packaging. For price, specifications and other details please contact us
